The devastation caused by Hurricane Katrina is a wake-up call. It is a call for every American to pay attention to the destruction we risk by allowing human-induced(导致的) climate change to continue. It is impossible to prove that Hurricane Katrina was caused by global warming, or even that human activities made the storm more severe. However, a paper published in the scholarly journal Nature reports that the force of dangerous hurricanes has increased by 50% during the last 50 years. It also reports that a global warming-induced rise in temperature near the ocean’s surface has probably contributed to this increase in dangerous storms, and thus to property(财产) damage and human death.
On August 30, the Los Angeles Times summed up(总结) the view of many scientists who agree that if the frequency of hurricanes does not decrease in the next few years, then we will be fairly certain that humans, and not natural storm cycle, are at the root of the problem. I believe there is at least a chance that by reducing U.S. reliance on fossil fuels for energy, we can prevent future tragedies like Hurricane Katrina. Let the change begin now.
There are many ways to reduce the volume of greenhouse gas emissions. My family drives the most fuel-efficient car we can afford, but I prefer to take public transportation whenever possible. My family buys locally grown food instead of produce that was transported thousands of miles on fuel-burning vehicles. We also replaced our incandescent light bulbs（白炽灯泡）with more energy-efficient compact fluorescents（荧光灯）. This might sound like a trivial move, but the Union of Concerned Scientists reports that if every household in the United States replaced one incandescent bulb with a compact fluorescent, it would have the same effect on U.S. carbon-dioxide emissions as removing 7.5 million cars from the roads. Now think if every household replaced not just one but all of their incandescent bulbs!
The United States, with just five percent of the world’s population, is responsible for close to one quarter of greenhouse gas emissions worldwide, yet our country is doing far less than most European nations to fight global warming. We don’t have to sacrifice our lifestyles; Europeans enjoy the same standards of living as Americans. So what are we waiting for? It is time to act.

There is a beautiful story about a child playing with a vase his mother had left on the table for a few moments.

But the hand was stuck fast（牢固地）. How would they get it out? The father suggested 20 the vase but it was quite valuable and the child’s hand might be cut in the 21 _. Yet he knew that if all else 22 there would be no other alternative.
So he said to the boy, “Now, let’s make one more 23 . Open your hand and stretch your 24 out straight, as I’m doing, and then pull!” “ 25 Dad,” said the boy, “if I do that I’ll 26 my penny!”
The boy had had a coin in his hand 27 and was holding it 28 in his tight little fist. And he wasn’t 29 to open his hand and lose it. But 30 he opened his hand it came out of the vase easily.
The father said to the boy, “What are you holding onto so tightly as to hinder (阻碍) your walk with God? That vase can be 31 to the entrance to the Kingdom of God. It is narrow yet quite 32 to pass in, but first you must open your hand to God and 33 earthly（世俗的）things to fall. If we keep our fists 34 and hold fast to what we have and keep it for ourselves, we will be unable to 35 hold of the hand of God. Open your hand to the hand of God and you will see great things take place.”
